Materials Data on Sn2Pd by Materials Project

PdSn2 crystallizes in the tetragonal I4_1/acd space group. The structure is three-dimensional. Pd is bonded in a 8-coordinate geometry to one Pd and eight Sn atoms. The Pd–Pd bond length is 2.90 Å. There are a spread of Pd–Sn bond distances ranging from 2.85–2.88 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 7-coordinate geometry to four equivalent Pd and one Sn atom. The Sn–Sn bond length is 2.96 Å. In the second Sn site, Sn is bonded to four equivalent Pd atoms to form a mixture of distorted edge and corner-sharing SnPd4 tetrahedra.

Materials Data on Ce(Sn2Pd)2 by Materials Project

CePd2Sn4 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ce is bonded in a 8-coordinate geometry to four equivalent Pd and ten Sn atoms. All Ce–Pd bond lengths are 3.53 Å. There are a spread of Ce–Sn bond distances ranging from 3.40–3.55 Å. Pd is bonded in a 6-coordinate geometry to two equivalent Ce and six Sn atoms. There are a spread of Pd–Sn bond distances ranging from 2.74–2.82 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 8-coordinate geometry to four equivalent Ce, two equivalent Pd, and two Sn atoms. There are one shorter (2.87 Å) and one longer (3.03 Å) Sn–Sn bond lengths. In the second Sn site, Sn is bonded in a 6-coordinate geometry to one Ce, four equivalent Pd, and one Sn atom.
